Wordpress - Show parent category AND subcategory name in subcategory archive URL

Question

I\'m having some trouble with Wordpress category/subcategory archive URLs.

For example, I want to be able to display this archive:
http://fa

Answer 1

This happens because you chose category and subcategory from the right options tick boxes when editing the entry. Choose only the subcategory box in every entry and it will show the nested URL.
